Vertebrata
Vertebrata is a group that contains various organisms which possess vertebrae (backbones). Animals that belong to the group are called vertebrates, and they include mammals, birds, fish, amphibians, and reptiles. The backbones in the animals extends from the head to the tail, and it encloses and protects the main nerve cord. The body of vertebrates is divided into trunk, and tail regions. They also possess a unique tube shaped brain, a distinct head, and three pairs of sense organs.
Oyster is a type of aquatic organism that significantly require oxygen for its survival and other metabolic processes.
A Population may be defined as the group of individuals belonging to the same species living in the same area at a particular time period. It includes the members of the same species.
The population of oysters requires at least 2-3 ppm of dissolved oxygen in order to survive in the aquatic environment. But if this amount of dissolved oxygen may alter it may significantly affect the population of oysters.
The higher level of dissolved oxygen is not a reason for much concern, but lower levels may be the potent cause for the reduction of the oyster population within the ecosystem.
Therefore, the Oyster is a type of aquatic organism that significantly require oxygen for its survival and other metabolic processes.
